Title: Improvements in resistance controllers for arc welding
IPC: B23K9/10
Filed: 1941-07-07
Abstract: 547,547. Variable resistances. LINCOLN ELECTRIC CO., Ltd., and CLIPSHAM, G. F. July 7, 1941, No. 8579. [Class 37] A control resistance for arc welding is operated by a foot pedal.

Patent GB-744415-A (GB)
Title: Improvements in or relating to a process for chlorinating titaniferous materials
IPC: C22B1/24
Filed: 1953-03-27
Abstract: Titaniferous iron material is mixed with a carbonaceous material such as coal or coke and charged into a chlorinator in the form of briquettes which are rected at 500-800 DEG C. in a static bed with sufficient chlorine to convert a major portion of the iron and titanium values to volatile chlorides but not more than the theoretical quantity to react with substantially the whole of said values, at a rate (preferably a velocity at 700 DEG C. of 0.08-0.13 feet per second) sufficient to ensure excess chlorine in the tail gases; the residium from the chlorinating process is removed and separated, e.g. by screening, into a dust-like gangue and lumps of unchlorinated and partially chlorinated briquettes which are reacted with the excess chlorine in the tail gases from which said chlorides have been separated.  The second chlorination may be performed in a second chlorinator, or in the same chlorinator using an additional quantity of briquettes and, if necessary, chlorine.  In a modification chlorine may be introduced in a similar quantity and at a similar velocity into a second chlorinator containing lumps of unchlorinated and partially chlorinated briquettes, and the chlorine recovered from the tail gases reacted with briquettes in the first chlorinator. Operation in the first chlorinator may be made continuous by removing the residue material as it is formed and charging additional briquettes.  By introducing additional chlorine into the second chlorinator, and adjusting the flow in either or both stages, substantially 100 per cent chlorine utilization efficiency may be obtained.  If desired a third chlorination may be performed after screening the residue from the second stage to remove unreacted materials, using chlorine obtained in part from the tail gases of the second stage.  In the example, 1000 parts by weight of briquettes comprising 526 parts of titanium dioxide, 40 parts magnesium oxide and 72 parts iron oxide were charged into a 24 inch deep bed in a chlorinator and externally heated to 700 DEG C. 918 parts by weight of chlorine was passed in at 0.11 feet per second and the tail gases passed through condensers which successively removed ferric and titanium chlorides, the bed being maintained by the addition of briquettes to the extent of 20-40 per cent of the original charge, after which a sharp rise in the chlorine loss indicated the completion of the first stage of the process.  The residue was removed and titaniferous lumps collected on a screen and placed, together with two similarly produced residues in a second chlorinator, through which the chlorine from the tail gas of the three runs was passed at a velocity of 0.08 feet per second at 700 DEG C.  Titantium tetrachloride and ferric chloride were condensed from the tail gases as before.

Abstract: 958,764. Endless conveyers. DURKOPPWERKE A.G. March 5, 1963 [March 30, 1962], No. 8746/63. Heading B8A. An endless suspension conveyer having a preselectable article ejecting means comprises a carriage 2 propelled along overhead rails 5 by means of a continuous driven chain 1, a carrier 11 depending from the carriage 2 having a support bracket 12 at its lower end, a pivoted article holding flap 14 at its upper end, and a bolt lever 17 which is released at the ejection station from a holding flap locking position by means of a mechanical pattern set on the carrier 2 coinciding with a pattern set at said station. The mechanical pattern on the carrier 2 comprises two banks of cams 7 set by means of press keys 6. Rollers 8 on a control device " P " engage the cams 7 whereupon a presser 9 on a pivoted tube 24 is adapted to swing into the travelling line of a roller 23 mounted on the bolt lever 17. The engagement of the roller 23 with the presser 9 pivots the lever 17 relative to the carrier and away from a stop face 21 on the holding flap 14. The weight of the overhanging portion of the article 10 causes the flap 14 to pivot and the article is released, after which a further cam 26 on the carrier 2 engages a roller 27 secured to a bracket 28 on the tube 24 and returns the tube 24 to its initial position. The tube 24 may be prevented from moving to its operating position by means of a lever 29 having a pawl at one end which engages a stop 30 on the bracket 28. This lever 29 is operated through linkages 31, 32, 33, 34 by means of a key 35 depressable by a deposited article at the ejection station.

Abstract: 127,699. Curran, C. J. May 27, 1918. Cupped articles.-To economize power and enable mechanically-operated presses to be used in heading and tapering metal bases of cartridges &c., the head portion of a plain cupped blank is first pressed, within a restricted die space, to produce a plurality of thickened and indented zonal areas within the circumference of the cylindrical part of the blank, and is then pressed, in an unrestricted die space, to produce the final form having a rim or bead extending beyond the circumference of the cylinder, the cylinder at the same time receiving the required taper. The plain blank a, Fig. 1, is placed within a socket d on a die of tapering form, the diameter being least at its upper end. The upper surface is provided with a recess k and may also have a slight annular depression o. The upper die c has a projecting nose h, annular projection m, shoulder r, and circumferential lip t. These dies bring the blank to the form shown in Fig. 3, which also shows the dies for effecting the completion of the process. The lower die is of tapering form, the diameter being greatest at its upper end, which is level with the socket Z. The upper die W has a nose 5, stepped portion 11, and depending portion 12 to restrict outward flow of metal. The action of these dies brings the head to the final form shown in Fig. 5, and at the same time the wall b is caused to contract into contact with the tapered inner die, spring out again, but not to its original diameter, when the pressure of the upper die is removed. Modified forms of the die W are described, in one of which the die is bounded by a set-back portion in place of the lip 12. A modified form of the die c is also described in which the shoulder r is replaced by a rib only slightly less prominent than the projection m.
